Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1-4 As shown, an automatic cleaning device for Chinese medicinal herbs includes a first identification component 1, a first sorting component 3, a first cleaning structure, and a second cleaning structure. The first identification component 1 is mounted on a first conveyor belt 2. A second conveyor belt 5 and a third conveyor belt 6 are connected to the end of the first conveyor belt 2. The first sorting component 3 is located between the second conveyor belt 5 and the third conveyor belt 6. The first sorting component 3 includes a baffle 301, which is rotatably mounted on the first conveyor belt 2. The first identification component 1 uses image recognition technology to identify the type of Chinese medicinal herbs and determine whether they require low-frequency cleaning (powerful decontamination, suitable for hard herbs such as roots and stems) or high-frequency cleaning. The Chinese medicinal herbs are gently cleaned (suitable for delicate herbs such as flower petals). The herbs that are cleaned with low frequency are blocked by baffle 301 from the third conveyor belt 6 and fall into the second conveyor belt 5 to enter the first cleaning structure for cleaning. Otherwise, they enter the second cleaning structure for cleaning. Both the first and second cleaning structures use ultrasonic cleaning. After cleaning, the herbs are judged by the second identification component 15 on the detection component set at the end of the first and second cleaning structures to determine whether they are clean. If they are not clean, they are sent back to the first conveyor belt 2 via return conveyor belt 13 to repeat the above steps. If they are clean, they enter the next process via DC conveyor belt 14.

[0020] like Figure 1-4As shown, the second cleaning structure is mainly used for gentle cleaning, using ultrasonic high-frequency cleaning (generally above 100kHz). The medicinal herbs being cleaned are mostly those with an overall density less than the cleaning solution (generally water). Therefore, a limiting structure 9 is needed to submerge them in the water. The second cleaning structure includes an upper limiting structure 9, a second chain conveyor belt 10, and a second cleaning box 11. The second chain conveyor belt 10 is fixedly installed inside the second cleaning box 11. The conveyor belt surface is perforated to facilitate contact between the medicinal herbs and the solution. The surface of the second chain conveyor belt 10 is covered with rubber to increase friction and facilitate the transport of the medicinal herbs. The second chain conveyor belt 10 has a U-shaped cross-section to facilitate entry and exit from the second cleaning box 11. An upper limiting structure 9 is provided at the top gap of the second chain conveyor belt 10. The gap is set to the average suitable thickness of the sampled medicinal herb plants. The upper limiting structure 9 restricts the upward movement of the medicinal herbs, ensuring that the bottom of the medicinal herbs is in contact with the upper limiting structure 9 and the second chain conveyor belt 10 respectively for easy transport. The input end of the second chain conveyor belt 10 is connected to the first conveyor belt 2, and the output end of the second chain conveyor belt 10 is connected to the detection component. The upper limit structure 9 includes a U-shaped upper pressure plate 901. The bottom of the U-shaped upper pressure plate 901 is provided with multiple sets of receiving grooves 902 evenly spaced. Multiple sets of sliding grooves 9021 are symmetrically provided on both sides of the receiving grooves 902. A rolling component 903 is provided in the sliding groove 9021. The rolling component 903 includes a spring 9031, a second roller 9032, a limiting rod 9033, and a pressure plate 9034. The limiting rods 9033 are fixed on both sides of the second roller 9032. A limiting rod 9033 is provided in each of the two symmetrical sliding grooves 9021. The pressure plate 9034 is slidably provided in the sliding groove 9021. The bottom of the pressure plate 9034 is rotatably provided with a limiting rod 9033. A spring 9031 is provided between the top of the pressure plate 9034 and the top wall of the sliding groove 9021. The lower half of the second roller 9032 protrudes from the receiving groove 902. The second roller 9032 is in direct contact with the Chinese medicinal materials. The rolling friction of the second roller 9032 reduces damage to the Chinese medicinal materials during transportation. The second roller 9032 is set perpendicular to the U-shaped upper pressure plate 901. The receiving groove 902 can be continuous, that is, the receiving groove 902 along the entire length of the bottom is connected. The second roller 9032 is continuously set, with almost no gap between the two second rollers 9032, to prevent the Chinese medicinal materials from getting stuck in the gap and causing damage. At the same time, since different Chinese medicinal materials have slight differences in size, the second roller 9032 is set in a way that can move up and down in the sliding groove 9021 to prevent excessive pressure on the Chinese medicinal materials from causing damage. The spring 9031 is made of a low elastic modulus material (such as silicone rubber), that is, even the small stress inside the Chinese medicinal materials can push the second roller 9032 to move upward, preventing the Chinese medicinal materials from being damaged by excessive bending over a long period of time.

[0021] like Figure 1As shown, the first cleaning structure mainly uses low-frequency ultrasonic cleaning (generally 20-50kHz). The first cleaning structure includes a first chain conveyor belt 7 and a first cleaning tank 8. The first chain conveyor belt 7 is fixedly installed inside the first cleaning tank 8. The input end of the first chain conveyor belt 7 is connected to the first conveyor belt 2, and the output end of the first chain conveyor belt 7 is connected to a detection component. The overall density of the Chinese medicinal materials entering the first chain conveyor belt 7 is generally greater than that of the cleaning solution, and they will fall into the water along with the first chain conveyor belt 7, therefore no additional restraint is required. The first cleaning tank 8 and the second cleaning tank 11 are both existing ultrasonic cleaning devices, and details will not be elaborated upon.

[0022] like Figure 1 As shown, the detection unit includes a main conveyor belt 12, a return conveyor belt 13, and a direct current conveyor belt 14. A second identification component 15 is located at the top end of the main conveyor belt 12, and the second identification component 15 has the same structure as the first identification component 1. A second sorting component 16 is rotatably located at the top end of the main conveyor belt 12, and the structure of the second sorting component 16 is the same as the first sorting component 3. The return conveyor belt 13 and the direct current conveyor belt 14 are connected to the end of the main conveyor belt 12, and the end of the return conveyor belt 13 is connected to the input end of the first conveyor belt 2. The second identification component 15 in the detection unit identifies whether the Chinese medicinal materials are clean by comparison. Cleaned materials proceed to the next process via the direct current conveyor belt 14, while uncleaned materials are returned to the first conveyor belt 2 via the return conveyor belt 13 for further cleaning.

[0023] like Figure 1 As shown, the system also includes a second conveyor belt 5 and a third conveyor belt 6. The third conveyor belt 6 is connected at both ends to the first conveyor belt 2 and the second chain conveyor belt 10, respectively. The second conveyor belt 5 is connected at both ends to the first conveyor belt 2 and the first chain conveyor belt 7, respectively. Infrared detectors 4 are installed at the top of both ends of the second conveyor belt 5 and the third conveyor belt 6, and are electrically connected to the control unit. The infrared detectors 4 at both ends record the quantity of Chinese medicinal herbs fed in and whether the corresponding conveyor belt is fully loaded. When both ends detect the presence of Chinese medicinal herbs, it indicates that the corresponding conveyor belt is fully loaded, and the corresponding conveyor belt and the first conveyor belt 2 stop rotating until the Chinese medicinal herbs need to be sent into the corresponding cleaning box. The quantity of Chinese medicinal herbs fully loaded on the corresponding conveyor belt is the cleaning capacity of the corresponding cleaning box.

[0024] like Figure 2As shown, the first sorting component 3 includes a baffle 301, a first roller 302, a rotating rod 303, a fixed plate 304, a rack 305, a transmission gear 306, a connecting rod 307, and a motor 308. The rotating rod 303 is rotatably mounted on the fixed plate 304. The baffle 301 is fixedly mounted on the top of the rotating rod 303. Multiple first rollers 302 are provided on both sides of the baffle 301 along the length direction. The transmission gear 306 is provided at the bottom of the rotating rod 303. The rack 305 is slidably mounted at the bottom of the baffle 301. The transmission gear 306 meshes with the rack 305. The motor 308 is fixedly mounted at the bottom of the baffle 301. An eccentric wheel is provided at the output end of the motor 308. The connecting rod 307 is rotatably mounted on the outside of the eccentric wheel. The connecting rod 307 is rotatably connected to the rack 305. When motor 308 rotates, it drives connecting rod 307 to move, which in turn drives rack 305 to reciprocate. One rotation of the motor corresponds to one reciprocating motion of rack 305, which in turn drives rotating rod 303 to rotate once, i.e., baffle 301 rotates once. Therefore, motor 308's half-turn rotation or no rotation is a response to the control unit's command after identification component 1 identifies the medicinal materials. If the medicinal materials are of the same type (same cleaning frequency) as the previous type, it will not rotate; otherwise, it will rotate half a turn. When baffle 301 blocks one side of the conveyor belt, the medicinal materials will flow to the other side, thus achieving the screening of medicinal material types. The subsequent detection components operate on the same principle.

[0025] like Figure 1 As shown, the first identification component 1 includes a U-shaped support plate 102 and an image acquisition device 101. The image acquisition device 101 is fixedly mounted on the top of the inner wall of the U-shaped support plate 102. The image acquisition device 101 is electrically connected to the control unit, which is electrically connected to the first sorting component 3 and the second sorting component 16. The control unit is also electrically connected to the storage unit. The data acquired by the image acquisition device 101 is transmitted to the control unit, which compares it with the data in the storage unit to determine the type of Chinese medicinal materials or whether the Chinese medicinal materials have been cleaned. This allows the control unit to determine the direction of the first sorting component 3 and the second sorting component 16, thereby achieving the classification of the Chinese medicinal materials (including type and whether cleaning is complete).

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
